LIGHTING APPARATUS FOR GAS BURNEBG.

Application filed March 12, 1927. Serial No. 174,982.

\ My invention relates to gas igniting apparatus of the type in which the ignition 1S accomplished by the proper elements-through l the actuation of the gas valve.

The particular object of m invent-ion is to provide means to ignite t e gas immediately it begins to escape from the burner, and to effect this lighting automatically while the valve is in the process of opening.

matic locking of the igniter out of operative.

position so as to be remote from the heat of the flame when not exercising its function, vand its release from this locked position when the valve is returned to its closed position.

I have illustrated my invention by the accompanying drawing in which,-

Fig. 1 shows the apparatus installed on a horizontal gas pipe, the gas valve being shown in closed position;

Fig. 2 shows the valve partly open and the igniting device nearly ready to be disengaged from the actuating means;

Fig. 3 is the same, except that the igniter has been fully withdrawn from the position close to the burner, and is locked in this withdrawn position so that the valve may be oscillated without effect on the igniter;

Fig. 4 is a fragmentary side elevation of the apparatus, and

Fig. 5 is a sectional detail taken on line 5-5, Fig. 3.

Similar reference characters identify like parts in all views. 1

Referring to Fig. 1. 1 represents an ordinary gas burner, 2 the gas valve therefor and 3 the gas mains to and from the valve. These parts are conventional and employed on all burners. Q I

Fixed, on the spindle 4,0f the valve 2, is a segmental gear 5, engaging which is a rack-rod t3 .slidably mounted in bearings 7. and 8 in the frame 9. This frame is oscil-- latibly mounted on a" projection 10 of the "compressed and the arm 16 will abut on the valve, and is normally held n close relation to the burner 1 by means of the torsional spring 11. i

The valve 2 is actuated by the handle 12, which when moved in the direction of the arrow (see Fig. 1) opens the former and reciprocates the rack-rod 6 toward the burner. This movement compresses the helical spring 13. rotates the pinion 14 by its engagement with the rack portion 6, and also rotates the abrading wheel 15 engaging the pyrophorous metal plug 15'. This causes sparks to fly into the gas escaping from the burner 1. igniting the same.

For the sake of clarity I will hereinafter designate the different positions of the handle 12 to correspond to the respective figures in which it appears, as position one,- two and" three.

During the movement of thehandle 12 from position one to position two, opening the gas valve about half way, the lgniter will function and cause ignition of the gas. The spring 13, as previously noted, will be smooth portion of the rack-rod 6 (see Fig. 2). I

A further slight movement of the handle will cause the arm 16 to disengage the rackrod from the gear 5 and the spring 13, now under compression, will return the rack-rod to its original position in the frame 9.

A still further'movement of the handle will swing the frame 9 with the rack-rod into position three, at which time the do 17 fixed on the frame, will engage the late 18 pivotally mounted on the body portion of the valve 2, locking the frame and igniter in its fully withdrawn position,-or that farthest removed from the burner. At this point the valve 2 may be independently operated by the handle 12, to regulate the flame, as it is completely disconnected from the igniting elements.

When it is desired to fully close the valve, the handle is swung back into position one and in so doing a pin 19 in the handle will engage the heel 18' of the latch 18, throwing the latter off the dog 17 and allowing the frame 9, through'the agency of the spring 11, to swing back into position one, adjacent the burner. A. torsional spring 20 holds the latch 18 normally against the stop 21. Should the igniter elements fail to fire the gas on the first forward movement of the handle 12, the latter may be oscillated between (positions one and two, causing the abrading Wheel to act until ignition does take place.

The tension of the torsion spring 11 is sufficient to counteract any tendency of the rack-rod 6 becoming disengaged from the segmental gear 5 until position two is reacl1- ed by the handle 12, the disengagement of of on the horizontal one as I have shown it in my drawings.

And having thus described my invention, what I claim is 1. A lighting apparatus for gas burners, comprising a gas valve, an oscillatory frame, spark producing elements supported on said frame, a reciprocable rod in said frame adapted to engage said spark producing elements, means to reciprocate said rod simultaneously'with the actuation of said valve, means to actuate said valve, means to disengage said rod from its means of reciprocation during the opening movement of said valve, and means to locate and to hold said spark producing elements in non-operating position, whereby said valve may be actuated alone and independently of said spark producin, elements.

' 2. A lighting apparatus for gas burners, comprising a as valve, said valve to include plug and be y portions, means to actuate said gas valve, a. frame mounted on said body portion, a segmental gear fixed on said plug portion of said valve, a rod slidalbly mounted in said frame, rack teeth on said rod adapted to engage the teeth in said segmental ear, means to hold said rack teeth and sai gear teeth in engagement, means to on said body portion, a frame mounted on said projection, spark producing elements, including a pinion, a, pyrophorous plug and an abraiding wheel, mounted on said frame, a rod slidably and yieldingly mounted in said frame and adapted to engage said spark producing elements, rack-teeth on said rod adapted to engage said segmental gear, yielding means acting to swing said frame on its pivot and toward said burner, an arm on said segmental gear adapted to intermittenly engage said rod, a latch pivotally mounted in said valve body, a dog fixed on said frame,said dog and said-latch constitutingmeans to hold said frame and said spark producing elements in non-operative position, relative to said valve, whereby said dil valve may be operated independently of the actuation of said spark producing elements, and means to release said frame from its non-operative position and allow it to swing into operative position, substantially as shown and described,

d. A lighting apparatus for gas burners, comprisin a gas valve, an oscillatory'trame,

spark-pro acing elements on said frame,

means on said valve co-acting with means on said frame whereby said spark-producing elements may be actuated, backwardly and forwardly during a period starting with the opening of said valve and until said valve is substantially one-half opened, and means to thereafter separate and hold in separated relation the said co-acting means, whereby said valve may be actuated alone and independently ot the actuation of said spark producing elements,
